Subaru V10 Cluster Fuel Gauge

HI All.

Im pretty stuck here - im in the process of wiring in a G4+ Link to me V10 Subaru STI.

While things have been 'fun' to say the least, Ive come across the fuel level sensors as an input to the OEM ECU!  I cannot find how this signal eventually ends up at the fuel level gauge itself!

It is not indicated in the PNP Link ECU for the V10 if te fuel level sensor is an input / output.

The same applies to inputs like - Internal Blower switch, Rear defogger switch (why would these be monitored at all?)

I hope someone can shed some light!

Thanks,

Jared

You will not need to connect any of those inputs.  I dont know what the oem ecu does with them but our plugins dont have them connected and everything still functions ok.  

"The same applies to inputs like - Internal Blower switch, Rear defogger switch (why would these be monitored at all?)"

The factory ecu monitors electrical loads for idle up purposes.

 

Thanks gentleman! I finally found a Cluster wiring diagram hidden away - It seems like the signal is physically 'Teed' from the particular sensors. :)
